Nashville implements new traffic signal timing to protect pedestrians

NASHVILLE, Tenn. (WTVF) — Nashville has implemented a new traffic signal system at more than 100 intersections to protect pedestrians as part of the city's Vision Zero initiative aimed at eliminating traffic deaths and serious injuries.

The Nashville Department of Transportation has reprogrammed traffic signals around the downtown area to give pedestrians a 3-to-7 second head start before vehicles receive a green light. The system, called Leading Pedestrian Intervals or LPIs, allows people to step into crosswalks and begin crossing before cars can move.

"Leading pedestrian intervals are when the walking person comes on at a traffic signal ahead of the green light, and that allows people walking to step into the street and begin crossing before cars," said Regional Practice Leader Beth Os
